Kettlebells Vs Dumbbells - Which Method Returns Best Results?

By Russ Howe


It's a war which has raged on for the best part of ten years but, thanks to recent scientific research, today you will get a definite answer to the question: Kettlebells vs dumbbells - which method will give you the best results?

Before we do that, it is important to point out that using both approaches is always going to be far superior to limiting yourself to just one style. You will often hear people swearing by the use of just one protocol, all this does is limit your ability on the gym floor as each style comes with it's own plus points and negatives, therefore a combination of the two styles alongside other forms of training, such as yoga, interval training and body weight movements, would be optimal for achieving the goals set by most individuals.

However, a recent study pitted the kettlebell against free weights in a study to determine which method would return the greatest strength gains overall. The results were quite profound.

The study followed a protocol where Group A would be using a 16 kilogram weight to perform a six week program of swings, accelerated swings and goblet squats in an attempt to boost vertical leap, power clean and squat strength levels.

The free weights group performed a six week program of barbell squat, power clean and high pull using around 80% of their one rep max on each exercise.

After the six week course was over, the results were overwhelmingly in favor of free weight training. Barbell squats improved one rep max on squats by a huge 15%, whereas goblet squats only resulted in a 5% increase. Then the free weight group also enjoyed a 10% strength boost to their power clean and 4% vertical leap.

The kettlebell group lagged behind with only a 4% power clean boost and 1% vertical leap improvement. Given that this piece of kit is well known for it's explosiveness, a mere 1% boost to vertical leap strength was surprisingly low in comparison to what could be achieved through free weights.

If you want to base your training program purely on the scientific findings, then free weights clearly return the greatest strength gains.

However, this would be ill-advisable. A combination of various different techniques is the key to finding a well balanced, progressive training program which gives you a continuous plethora of new results. By limiting yourself to one training style, you are waving goodbye to various other techniques you could have picked up if you were only a bit more open-minded.

The best way to develop a well rounded training program is to use aspects of different training methods until you find something which works for you. It is not uncommon to see bodybuilders, who are primarily known to use free weights and machines, adopt exercises like swings into their routine from time to time.

The battle between kettlebells vs dumbbells will be one that undoubtedly cuts most gyms down the middle depending upon personal choice. However, the latest scientific research clearly documents one winner.
